Title: Chirp signal generation circuit
Inventor: KOBAYASHI HIDEO
IPC: H03B23/00
Filed: 1995-10-11
Abstract: PROBLEM TO BE SOLVED: To realize a high-precision chirp signal generation circuit with a sweep oscillator by converting a pulse width into a voltage by an integrator and using an AD converter to measure this voltage and obtaining a continuous frequency error to correct the frequency of an original chirp signal. SOLUTION: A waveform shaping circuit 5 shapes the waveform of the output high frequency signal of the chirp signal to output a shaped pulse. A pulse width-voltage converter 6 generates a voltage corresponding to the pulse width of the shaped pulse. An AD converter 7 converts the output of the pulse width-voltage converter 6 into a digital code. The output of the AD converter 7 is compared with the instantaneous frequency code of the chirp signal obtained from an instantaneous frequency code generation means (circuits 10 to 13) to detect the error, and the frequency of the chirp signal is corrected in accordance with the detected instantaneous frequency error. Thus, the high-precision chirp signal is generated because of frequency control of all of the chirp signal whose frequency is continuously changed.

Title: Toner concentration controller
Inventor: MORITA TAKAKAZU
IPC: G03G15/08
Filed: 1987-11-13
Abstract: PURPOSE:To control the temperature compensation of a toner sensor which is influenced by the change of the temperature of developer by using a temperature sensor already provided in an image forming device. CONSTITUTION:When real temperature of the developer is below (t) and the detected temperature by the temperature sensor 202 is (t) or above, a control means 203 controls an output from the toner sensor 201 to be VC. In such a case, the toner concentration is kept lower than at the time when a 1st set value is VA. When the detected temperature of the temperature sensor 202 becomes below (t) in such a state, 1st and 2nd set values are reset in VA and VB and the toner sensor 201 temporarily outputs the output VC since the toner concentration can not change suddenly from the concentration corresponding to the output VC from the toner sensor 201. It is assumed VC<VB, so that the image forming device 205 is not stopped and a display means 206 does not perform displaying. Thus, the temperature compensation of the toner sensor can be performed without malfunction.

Title: Image processing apparatus
Inventor: KATAYAMA AKIHIRO
IPC: G06K15/00
Filed: 1987-11-16
Abstract: PURPOSE:To enhance the grade of an image by judging whether the dot already typed in the processed region of the periphery of a noticeable pixel is present and quantizing the noticeable pixel corresponding to the judge result. CONSTITUTION:According to the value of a signal 510, a selector 19 outputs a signal 520 as a signal 400 when the signal 510 is '0' and outputs a signal 530 as the signal 400 when the signal 510 is '1'. However, the value of the signal 530 is '0'. That is, binarized data in the periphery of a noticeable pixel is investigated with respect to a pixel low in image density and, when there is a signal turning a dot ON in said data, the signal 520 becomes '1' and, therefore, the signal 400 to a threshold valve setting circuit 4 becomes '1' and, since a threshold value T1=300 is selected in the threshold value setting circuit, the dot of the noticeable dot is turned OFF necessarily. Further, when there is no signal turning the dot ON in the periphery of the noticeable pixel at this time, the signal 520 becomes '0' and, therefore, a threshold value T2=127 is selected in the threshold value setting circuit 4 and binarization processing is performed. Since the signal 530 is selected with respect to a pixel high in image density by the selector 19, the threshold value T2=127 is selected in the threshold value setting circuit 4 to perform binarization processing.

IPC: G01D3/028
Filed: 1992-10-02
Abstract: PURPOSE:To discriminate a signal component generated by the drift of a sensor from a state detecting signal when a small detecting state continues for a long time due to the state of an object to be controlled. CONSTITUTION:Offset correction is performed on the detecting signal of the yaw-rate sensor 1 of an automobile by inputting part of the detecting signal to a subtractor 2 as a subtraction signal through a filter circuit 4 constituted by connecting in series a first to a third filters 5-7 in three stages. When the output signals of the second and third filters 6 and 7 are monitored, it can be discriminated that detecting signals having a difference between them are not generated by the zero point drift of the sensor 1, but normal state detecting signals, when the detecting signals are outputted from the filters 6 and 7 and the execution of wrong zero-point drift correction is prevented by stopping the function of the third filter 7. Since the zero-point drift correction can be accurately performed with a simple constitution, an inexpensive zero-point drift correcting device can be provided for the sensor 1.

Abstract: PURPOSE:To correctly detect the sheet extinction and improve reliability by providing a reference voltage generating circuit in parallel with a constant- current power supply of a recording paper feeding DC motor and comparing both voltages to detect the sheet extinction of the recording paper. CONSTITUTION:The recording paper 2 is transferred by a platen roller 4 at a fixed speed at the time of printing and rewinding, a DC motor 100 is rotated at a nearly fixed angular velocity, and the voltage applied by a constant-current power supply 110 is almost constant. When the sheet extinction occurs in the course of printing, the voltage applied to the DC motor 100 is abruptly increased to the upper limit value. On the other hand, a reference voltage generating circuit 33 voltage-divides the constant voltage from a constant-voltage power supply 35 with a potentiometer 31 and generates the reference voltage of the nearly intermediate value of the voltage applied to the DC motor 100 based on the existence or nonexistence of the recording paper, thus the sheet extinction can be detected and displayed on an indicator 34 via the comparison by a comparing circuit 32. Accordingly, the sheet extinction can be correctly detected even if the recording paper has stains, perforations, etc.
